Implementation Reference
- src/tools/utilities.ts:70-93 (handler)The handler function that executes the 'accept_dialog' tool logic. It extracts optional promptText from args, gets the Firefox instance, calls firefox.acceptDialog(promptText), and returns success or error response.export async function handleAcceptDialog(args: unknown): Promise<McpToolResponse> { try { const { promptText } = (args as { promptText?: string }) || {}; const { getFirefox } = await import('../index.js'); const firefox = await getFirefox(); try { await firefox.acceptDialog(promptText); return successResponse(promptText ? `✅ Accepted: "${promptText}"` : '✅ Accepted'); } catch (error) { const errorMsg = (error as Error).message; // Concise error for no active dialog if (errorMsg.includes('no such alert') || errorMsg.includes('No dialog')) { throw new Error('No active dialog'); } throw error; } } catch (error) { return errorResponse(error as Error); } }
- src/tools/utilities.ts:9-21 (schema)The input schema and metadata definition for the 'accept_dialog' tool.export const acceptDialogTool = { name: 'accept_dialog', description: 'Accept browser dialog. Provide promptText for prompts.', inputSchema: { type: 'object', properties: { promptText: { type: 'string', description: 'Text for prompt dialogs', }, }, }, };
- src/index.ts:103-147 (registration)Registration of the handler for 'accept_dialog' in the toolHandlers Map used by the MCP server.const toolHandlers = new Map< string, (input: unknown) => Promise<{ content: Array<{ type: string; text: string }>; isError?: boolean }> >([ // Pages ['list_pages', tools.handleListPages], ['new_page', tools.handleNewPage], ['navigate_page', tools.handleNavigatePage], ['select_page', tools.handleSelectPage], ['close_page', tools.handleClosePage], // Script evaluation - DISABLED (see docs/future-features.md) // ['evaluate_script', tools.handleEvaluateScript], // Console ['list_console_messages', tools.handleListConsoleMessages], ['clear_console_messages', tools.handleClearConsoleMessages], // Network ['list_network_requests', tools.handleListNetworkRequests], ['get_network_request', tools.handleGetNetworkRequest], // Snapshot ['take_snapshot', tools.handleTakeSnapshot], ['resolve_uid_to_selector', tools.handleResolveUidToSelector], ['clear_snapshot', tools.handleClearSnapshot], // Input ['click_by_uid', tools.handleClickByUid], ['hover_by_uid', tools.handleHoverByUid], ['fill_by_uid', tools.handleFillByUid], ['drag_by_uid_to_uid', tools.handleDragByUidToUid], ['fill_form_by_uid', tools.handleFillFormByUid], ['upload_file_by_uid', tools.handleUploadFileByUid], // Screenshot ['screenshot_page', tools.handleScreenshotPage], ['screenshot_by_uid', tools.handleScreenshotByUid], // Utilities ['accept_dialog', tools.handleAcceptDialog], ['dismiss_dialog', tools.handleDismissDialog], ['navigate_history', tools.handleNavigateHistory], ['set_viewport_size', tools.handleSetViewportSize], ]);
- src/index.ts:150-191 (registration)Registration of the 'accept_dialog' tool definition in the allTools array returned by listTools.const allTools = [ // Pages tools.listPagesTool, tools.newPageTool, tools.navigatePageTool, tools.selectPageTool, tools.closePageTool, // Script evaluation - DISABLED (see docs/future-features.md) // tools.evaluateScriptTool, // Console tools.listConsoleMessagesTool, tools.clearConsoleMessagesTool, // Network tools.listNetworkRequestsTool, tools.getNetworkRequestTool, // Snapshot tools.takeSnapshotTool, tools.resolveUidToSelectorTool, tools.clearSnapshotTool, // Input tools.clickByUidTool, tools.hoverByUidTool, tools.fillByUidTool, tools.dragByUidToUidTool, tools.fillFormByUidTool, tools.uploadFileByUidTool, // Screenshot tools.screenshotPageTool, tools.screenshotByUidTool, // Utilities tools.acceptDialogTool, tools.dismissDialogTool, tools.navigateHistoryTool, tools.setViewportSizeTool, ];
- src/firefox/pages.ts:48-60 (helper)Low-level helper method in PageManagement class that handles accepting browser dialogs using Selenium WebDriver BiDi.async acceptDialog(promptText?: string): Promise<void> { try { const alert = await this.driver.switchTo().alert(); if (promptText !== undefined) { await alert.sendKeys(promptText); } await alert.accept(); } catch (error) { throw new Error( `Failed to accept dialog: ${error instanceof Error ? error.message : String(error)}` ); } }
